Varnish Controller 7.3.3 Release

• Support for loading a custom VCL for all VCLGroup per agent (see Agent Configuration).
• Support router maintenance TCP port and file (see Router Configuration).
• New -git-tag flag for vcli to specify tag to use for deployment (can be used for deploy, compile and validate).
• Set a default of 15 database connections if no other values were configured before. To go back to the previous default values, set VARNISH_CONTROLLER_DB_MAX_OPEN_CONN and VARNISH_CONTROLLER_DB_MAX_IDLE_CONN to 0.
• Fixed a bug where large CAA DNS responses would not be parsed properly for ACME certificates.
• Fixed a bug where EAB was required for ACME but not showing in the UI.
• Added documentation to the VCLI on random agent for ACME requests.
• Increased ACME logging for certificate renewal.
• Fixed a memory leak in the traffic router when the history routing rule was used after a GRPC plugin. History is now cleared upon removal of the history rule from the routing rule set.
• Add support to see the amount of objects purges with y-key and regular purges (see Invalidations).
• Add support to auto-remove agents and routers in container / autoscaling setups (see Brainz configuration).
• Fix Swagger documentation for certificates.
• vcli agent ls -v now only lists 10 deployed VCLGroups per agent and indicates if there are more than 10 with a “..(n more entries)” suffix.
• Built with Go 1.25.7.
• Fixed a bug where selecting a custom date for a API token would lead to a unresponsive UI.
• Added a missing permission in the UI for customsession.
